KILN FOR COKING PEAT OR SIMILAR MATERIAL.

SPECIFICATION forming part of Letters Patent No. 793,260, dated June2'7, 1905.

Application filed November 15, 1901. Serial No. 82,370.

To (Ml m/wnt it may (on/earn:

Be it known that l, hlAlt'lIN ZIlcaLnn, engineer, of 3Kaiser-Friedrichstrasse, Berlin- Seln'ineberg. Germany, have inventedanew and useful lmprovement in Kilns fol-Coking Peat or SimilarMaterial, (for which I have made application for Letters Patent inGermany, liled September 26, 1901, and in England, tiled September 26,1901, No. 19,241,) of which the following is a specilication.

The present invention relates to improvements in furnaces tor cokingpeat or the like, and is more especially applicable to furnaces ot thekind in which the peatis heated in upright retorts of an elongated formf. (2., a form wherein the width of the retort is narrow as comparedwith the length thereof, the retort thus having short end walls and longside walls.

The improvements consist,essentially,in the tact that on the two ends ofthe upright retorts hollowspaces are separated otl' by means of a numberof superposed partitions, each partition being set nearer to the endwall of the retort than the one above it, and the gas produced in thisretort is able to escape quickly through the spaces occurring betweenthe partitions themselves and through the hollow spaces inclosed betweenthe partitions and the walls of the retort.

In order to enable the invention to be fully understood, reference ismade to the accompanying drawings, in which- Figure 1 is a verticalsection through the upper part of a retort constructed according to thisinvention. Fig. 2 is a vertical section upon the line 0 I), Fig. 1. Fig.3 is a horizontal section upon the line A B, Fig. 1.

The upper part of the retort as represented in the drawings is composedof separate rings arranged one above the other. In the uppermost ringthe hollow spaces a Z) are separated off by partitions c (I, which areshown cast in one piece with the ring. These spaces (1 and 71communicate with each other by means of two passages f, open at thebottom and extending along the side walls of the retort. In the secondring from the top, partitions are situated somewhat nearer to the endwalls of the retort, so that there remain between the partitions 17 andopenings 0, which are preterably enlarged by bemling inward the loweredges of the partitions (a (Z, as shown in Fig. 1. The partitions in thethird ring from the top are placed a little nearer to the end walls 01the retort than the partitions r/ /I and in the same manner are placedthe partitions of the fourth ring with regard to those of the thirdring. The spaces in the second and third rings are designated by theletters a 6' and a 0, respectively. Owing to this arrangemel'it, thetree space of the retort is enlarged toward the bottom somewhat in theForm of a pyramid. Uonserpientlythe heating-surface oi the retort alsois enlarged. The gases produced in the retort escape through theopenings 0 into the hollow spaces separated oil by the partitions e (I 1l1 and are drawn oil through the conduit w. The gases produced near tothe side walls of the retort pass into the passagesf, which, as stated,are open at the bottom. These passages f therefore do not only formconnections between the spaces It 7), but they form in themselvespassagcs't'or the escape of gas from the retort.

As will be seen by reference to drawings, the openings r; are easilyaccessible from the top of the furnace by removal of the covers or plugsm, and stoppages can be thus easily dealt with.

1 claim- 1. A furnace tor coking peat and the like having an uprightretort of oval orelongated form in cross-section and superposedpartitions arranged near to the end walls in the interior of the retort,each partition being situated nearer to the end wall of the retort thanthe one above it, in such a manner that openings are formed between thepartitions, substantially as described.

2. A furnace for coking peat and the like i hzWing an upright retort ofelongated form,

and superposed partitions arranged near to the end walls in theinteriorot' the retort, each partition being situated nearer to the endwall of the retort than the one above so that openings as described areformed between the parto this specification in the presence of twosubtitions, the hollow spaces in the uppermost scribing witnesses. partof the retort separated off by the upper- MARTIN ZIEGLER. mostpartitions being connected by passages 5 f open at the bottom andextending along the Witnesses:
